Depreciation Methods

There are eight methods of depreciation available:

Straight-Line
Declining-Balance 1
Declining-Balance 2
DB1/SL
DB2/SL

This method uses the same principle as DB1/SL, but the declining-balance depreciation amounts are calculated according to the Declining-Balance 2 method.
User-defined
Manual

When you use the manual method, you must enter depreciation manually in either the FA G/L journal or the FA journal. The Calculate Depreciation batch job omits fixed assets that use the manual depreciation method. You can use this method for assets that are not subject to depreciation, for example, land.
